DETAILED DESCRIPTION

Some embodiments of the inventions relate to determining the context ofa computing device.

In some embodiments a remote request is received relating to a contextof a computer after the computer has been powered off. A sensor of thecomputer is turned on to obtain context information of the computer fromthe sensor. The obtained context information is provided from thecomputer to a remote device while the overall computer is still poweredoff (for example, the operating system is powered down).

In some embodiments a context aware circuit receives a remote requestrelating to a context of a computer after the computer has been poweredoff. The context aware circuit turns on a sensor of the computer toobtain context information of the computer from the sensor. The contextaware circuit also provides the context information to a remote devicewhile the computer is still powered off.

In some embodiments a system includes a sensor and an input/outputcontroller. The input/output controller receives a remote requestrelating to a context of the system after the system has been poweredoff, turns on the sensor to obtain context information of the systemfrom the sensor, and provides the context information to a remote devicewhile the system is still powered off.

The computer industry has recently been moving toward “context awarecomputing”. Context aware computing moves the increasingly ubiquitouscomputing device (for example, desktop, laptop, tablet, personal digitalassistant or PDA, Ultra Mobile Device or UMD, and/or smart phone, etc.)to a new level. In some embodiments this can occur by providingawareness to the current computing environment and also to theenvironment of the user. In response to this awareness according to someembodiments the computer helps the user by providing information that isrelevant to the user's current context.

There are several examples of context aware computing that may beimplemented according to some embodiments. For example, when a user isworking at home a context-aware laptop might show personal informationsuch as personal email, personal desktop, scores from the user'sfavorite sports teams, etc., and when the user is in the office it mightshow the user office information such as work email, work desktops, workfavorites, company stock ticker, etc. In another example, if a suddenstorm arises a context-aware calendaring application notifies the userthat 15 additional minutes will be necessary for travel time to theuser's next appointment. As another example, when a user moves fromoffice to office (or site to site) a context-aware laptop of the userautomatically reconfigures the default printer to the printer that isphysically the closest, and may also direct the user to that printer ifthe user is not familiar with that office. In another example, if a userreceives instant messages from the user's spouse, the messages appearwithout showing the content of the message if someone else is in theuser's office or cubicle. In this manner the user can later look at thecontent when the other person leaves the office or cubicle. Similarly,if the user is alone in their office or cubicle when an instant messageis received from the user's spouse that message is automatically shownto the user as it arrives. These examples are meant to be examples ofsome embodiments, but there are many other examples of the capabilitiesof such a context-aware platform according to some embodiments.

According to some embodiments context-aware applications may beimplemented even when the computer of the user is turned off, in asuspend mode, in a hibernate mode, etc., but another system isinterested in knowing about the context of the computer. For example, insome embodiments, a first computing device such as a laptop or otherdevice might include a GPS (Global Positioning System) device, anaccelerometer, a thermometer, an atmospheric pressure sensor and/orother context related devices coupled with and/or incorporated into thecomputing device. In some embodiments, even when the first computingdevice is turned off, a second computing device such as a PDA (forexample, with a different user than the first computing device) candetermine the context of the first computing device and the user of thatdevice using sensors within the applications of the first computingdevice. For example, the second computing device might determine theuser's location, travel speed, temperature information, etc., and beable to make a decision based on the information provided from both ofthe computing devices according to some embodiments.

FIG. 1 illustrates a computer 100 according to some embodiments. In someembodiments computer 100 is a desktop, a laptop, a tablet, a personaldigital assistant or PDA, an Ultra Mobile Device or UMD, a smart phone,and/or any other type of computing device. In some embodiments computer100 includes one or more central processing unit (CPU) 102 (orprocessor), a memory controller hub (MCH) 104 (or Northbridge), anInput/Output Controller Hub (ICH) 106 (or Southbridge), a memory 108, anAccelerated Graphics Port (AGP) device 110, a Peripheral ComponentInterconnect (PCI) device 112, a Universal Serial Bus (USB) device 114,a power management controller 116, flash memory 118, a networkconnection 120, a GPS device 122, a thermometer 124, an accelerometer126, an atmospheric pressure sensor 128, and/or other sensors 130.Active Management Technology (AMT) 132 such as Intel AMT may bedistributed within the ICH 106, the memory 108, the network connection120, and/or other elements in the system. A context aware subsystem(CASS) 134 may be included, for example, in the ICH 106. In someembodiments, many or all of the elements illustrated in FIG. 1 areresident on a printed circuit board (PCB) such as a motherboard.

A computer system such as computer 100 may include one or more centralprocessing units (CPUs) or processor(s) 102. The CPU(s) 102 may becoupled to a chip set (for example, via a bus). The chipset may includea memory controller hub (MCH) 104 including a memory controller coupledto a system memory such as memory 108. The system memory may store dataand/or sequences of instructions that are executed by the CPU(s) orprocessing device(s) included in the computing system. The MCH may alsoinclude, for example, a display controller coupled to a display. Thechipset further may include an input/output control hub (ICH) 106coupled, for example, to the MCH 104 via a hub interface. The ICH 106may be coupled, for example, to one or more input/output (I/O) devices.The ICH 106 may also be coupled to a peripheral bus (for example, aPeripheral Component Interconnect or PCI bus). A PCI bridge may becoupled to the PCI bus to provide a data path between the CPU(s) andperipheral devices.

With the release of Intel vPro™ technology, new capabilities have beenincorporated into computers that actually operate while the system isturned off. For example, Intel AMT, which is a portion of Intel vPro™technology, keeps part of the motherboard powered even when thecomputing system is turned off by the user. This small subsystem on themotherboard can respond to a remote request by a management applicationto do things such as power up the system, install an Operating System(OS) or application patch, etc., and then power the system back downagain. AMT 132 of the computer 100 can help to perform these types ofoperations. AMT 132 allows, among other things, a system to be powereddown but still respond to management requests over a network (vianetwork connection 120) to manage the system in this type of manner. Insome embodiments, these same capabilities allow for a remote system toobtain context information for the system 100 while the system 100 isstill shut down.

According to some embodiments, the AMT 132 and/or CASS 134 may be usedto respond to requests to provide context information when the system100 is powered up. In embodiments where system 100 is a desktop, forexample, this is sometimes a feasible option. However, in otherembodiments it may not be a feasible option since the system 100 ispowered down for some reason (for example, a desktop that has alreadybeen powered down, a laptop that has been powered down to conversepower, etc.). According to some embodiments, the AMT 132 and/or CASS 134may be used to respond to requests to provide context information whenthe system 100 is powered down.

In some embodiments, when system 100 has been powered off by a user,CASS 134 continues to be powered so that it can respond to remoterequests over a network (via network connector 120). CASS 134 respondsto remote requests that come in over the network connection 120 via theAMT subsystem 132. The CASS 134 turns sensors such as sensors 122, 124,126, 128, and/or 130 on and off as needed to collect context informationfor the system 100 and returns the collected context information to therequesting computer, for example, via AMT 132 and/or network connection120. As a result, authorized remote systems (for example, a PDA, aremote management system, and/or any other type of computing device) canobtain information about the context of the system 100 even when it ispowered down, and the remote system can use that obtained information toprovide context information to its own application and/or for other usessuch as system inventory, for example.

As discussed above, CASS 134 continues to be powered even when thesystem 100 is powered down. This enables CASS 134 to respond to remoterequests made, for example, over a network. Sensors 122, 124, 126, 128,and/or 130 allow the CASS to help the system 100 to determine itscontext. In some embodiments, sensors 122, 124, 126, 128, and/or 130 aretypically turned off in order to conserve power unless a request comesthrough the CASS 134 to turn on or more of these sensors on in order totake a measurement, for example.

In some embodiments AMT 132 allows, among other things, the system 100to be powered down but still respond to management requests over thenetwork to manage the system. CASS 134 allows further capabilities of aremote system to obtain context information relating to system 100. Insome embodiments CASS 134 is logic added to the ICH 106 that allows thesystem 100 to respond to remote requests for context information. Insome embodiments, these remote requests may be made over the AMT 132network stack. In some embodiments, CASS 134 turns on one or more or allof the GPS sensor 122, the thermometer 124, the accelerometer 126, theatmospheric pressure sensor 128, and/or other sensors 130 to takereadings of the context and/or environment of the system. The CASS 134is also able to turn those sensors off after the readings are taken inorder to conserve power. In some embodiments GPS 122 is a GlobalPositioning System device used to obtain location information such as,for example, latitude, longitude, and/or altitude of the system 100. Insome embodiments thermometer 124 is a sensor to determine an ambienttemperature of the location of the system 100. In some embodimentsaccelerometer 126 is a sensor to determine a direction of travel and anacceleration of the direction of travel of the system 100. This canallow, for example, a determination of the speed of the system, forexample. In some embodiments the atmospheric pressure gauge 128 is asensor used to determine an atmospheric pressure around the system 100.This information may be used, for example, to track and predict weatherpatterns and/or to estimate the altitude of the system 100. In someembodiments, the other sensors 130 may be one or more sensors thatperform functions such as, for example, detecting a presence of the usernear the system 100, detecting presence of other people near the system100, detecting body temperature(s), and/or detecting humidity levels,etc.

FIG. 2 illustrates a sequence diagram 200 of an exemplary remote requestbetween a remote system 202, an AMT 204, a CASS 206, and/or a sensor208. Sensor 208 may be any sensor such as but not limited to sensors122, 124, 126, 128, and/or 130 of FIG. 1, for example.

In the sequence diagram 200, a request to get a value is made from theremote system 202 to the AMT 204. The AMT 204 passes the request alongto the CASS 206, and the CASS 206 then turns on the sensor 208. Then theCASS 206 passes a request along to the sensor 208 to obtain a value fromthe sensor (for example, a location value in embodiments where sensor208 is a GPS device). The value is then returned from the sensor 208 tothe CASS 206 and the CASS then turns off the sensor 208. The value isthen returned from the CASS 206 to the AMT 204, and passed along to theremote system 202. While FIG. 2 illustrates a single sensor 208, in someembodiments the get value request may be a request for several valuesthat are requested at once and obtained by the CASS 206 at the same timefrom several sensors 208. In some embodiments, the functions performedin the sequence diagram 200 are performed while a system including theAMT 204, the CASS 206, and/or the sensor 208 is turned off with systempower only being supplied to some or all of the AMT 204, the CASS 206,and/or the sensor 208. In some embodiments all elements of FIG. 1 and/orFIG. 2 may not be necessary. For example, in some embodiments, the CASSmay be implemented without the AMT, and/or in some embodiments the AMTand the CASS may be included in one device, unit, logic, hardware,and/or software, etc.
